If you notice, those are all perfect cubes lol. I am doing algebra II in 10th grade now, and we are doing logarithms and such. whenever I see a perfect cube, it makes me happy, because they generally make the problems easier lol.

wow haha. but i really don't have a favorite number. if anything it would be like 64 or 8 or 27 i guess

how exactly do you check for continuity? my DMM explains it like this (and I don't get it): "Touch the test leads across the circuit you want to measure. 'shrt' appears and the buzzer sounds if the circuit resistance is less than about 50 ohms (meaning the circuit is continuous or shorted)...

well their 100 might be overpowered too, making it around 110 or something. But that's good that you got the problem fixed!

yeah I would like to know what OD these are exactly, cause I am planning on using these with my ~250mW red laser, and I would like to know it won't blind me lol.

And remember that if you are making your own driver there is some manual labor needed. For example, I started making a red burner, and my circuit just doesn't work. I've checked all the components, and new batteries, and everything, but the circuit just doesn't work, so now I'm stuck! however...

I'm pretty sure everything that could possibly go wrong has. I was working with the circuit today and found that the negative lead wasn't my problem at all. The circuit just doesn't work for some reason. I unsoldered it and re soldered it and nothing. I checked the resistor, and tried to check...

jay, if I have the negative just touching that metal screw-in-piece, is it routed all the way to the negative terminal?

Ok I've already fried one diode in this project and have absolutely no idea why. When I checked the current, it either read 1,200 mA or 300 mA or 600 mA, depending on how it was feeling (meaning I have no idea). I had checked and double checked my circuit, and still got an LED. Now I am working...

Well after much thought of easy ways I could ground myself, I have thought of one good way. my work place is really close to a window, so I thought maybe if I stuck a metal stake in the ground, attached wire to it, and threaded it through the window. Then I would tie it to my wrist. would that...

Re: Ambitious burner project idea & heatsink quest yeah I don't see any problems. The heat would be a BIT of a problem, but just don't keep it on too long. The thing is small enough, so you can feel when it gets too hot and when you need to shut it off.

well I have put it and the batteries in at the same time, and it did fit, so I think its alright, even though i think I did cut it below that wider part. lol. if it doesn't work out, I can get another MXDL and do it better the second time and I forgot to mention, I would wrap the wire in...

jay, thanks! I'll look around for some wire. actually, could I take a single thread from the multistranded wire or would that be TOO thin and flexible? and as for the threaded aluminum piece, I have already cut off the top with a hacksaw. I know, a little unconventional, but I don't have...

amk, I'm almost positive that the diode didn't die during extraction because the wires were still intact and everything looked good. But I guess that possibility is always there. As for pictures, I'll try to take some, but I don't know how much you guys are going to be able to see from them...

Jay and Chido, thanks for all those parts! I'll probably order those when I earn some more money. I already did order 2 more drives, though, so all I need are those parts and now batteries. also, thanks for that tip on the batteries! I can order the batteries and charger online right? because...

ok, this is what my schematic looks like. I took it off the little circuit board (next diode is going to have the circuit on it, NOT that little board), and soldered it all together. the multimeter read .336 A. which should be 336mA I am probably doing it wrong, and would like to try that 1...

Jay, yes I have confirmed that it is dead now. I'll have to order some more drives to harvest as I am not yet done with this! And about the smoking thing, I think it was a wire from my cap resting against the resistor, but I'm still not sure. As for the rest of the circuit, I checked to make...

THANK YOU!! this helped alot! I was sitting here waiting for an answer lol, but it was worth it! time to go get back to work! edit: WOW I am very pissed off right now. After I set everything up, I double checked the circuit, made sure everything was right, I hooked the diode up. I turn it on...

and then I just need a wire coming from the negative pin on the diode to touch the inside of the MXDL? as that will then carry the current to the tail cap? also, Daedal sent me a LM317 for that blu-ray circuit, will it work for this curcuit or will I need one rated at a higher current/voltage?

I have confirmed that the resistor is 3 ohms, but before I can put the circuit together, I still need to know how the batteries are faced, and where the current goes to get to the opposite terminal...
